Lol try fighting cancer with natural medicine. RIP Steve Jobs.

He apparently went for fruits - feeding the cancer with sugar.
It's worse than that. His pancreatic cancer was actually the very small minority that could have ended up NOT killing him.
But he ignored Western Medicine :)
Damn, to fight cancer you just have to avoid sugar? Like, seriously, all you have to do is just deplete your body of all energy stores? Man why didn't anyone else think of that?
You can start your own research for this concept with āWarburg effectā and āAnti-Warburg effectā
Thats all I can help, you donāt need to thank me.
Itās not a cure for all cancers, but it can certainly help with many. If someone has medically induced cancer thanks for āmiraculousā pharmaceutical injections developed at the speed of science, then fasting and avoiding sugar probably isnāt going to help at that point.
Or you can give chemo, actual poison, a shot at curing oneās cancer while destroying the rest of the body.
People sucked in mainstream medicine will forever deny the fact that nobody can tell them what cancer actually is, but will repeat to death "fighting it". The concept of not-living cells/pathogens attacking the living body is literally the con on which the entire industrialized medical industry is based.
Helth! or "When the solution is the poison killing your body, proudly pretending to help you since the 19th c.!"
Unironically yes, although "sugar" has to include starches as well
Most cancers require glucose to live
If you go on a keto or carnivore diet your body will still make a small amount of glucose but mostly you'll operate on fat and ketones
Guanabana has profound anti-cancer properties. Very difficult to procure outside of South America though.
This āsugar feed cancerā is very good example for the Bell curve meme phenomenon IRL.
Those on right curve easily believe it and become the āfewā that thrive without having to understand it deeply.
Many (in the middle of the curve) heard this but ignore because it sound like BS (especially in current medical textbooks)
But for those in the right curve those who actually put their proof of work into lengthy research and reading thru wall of texts
They become the fews that actually understand this and agree with the fews in the left curve
Yes, you can fend off cancer more effective (or even with very minimal chemotherapy) with your own āNatural house keeping mechanismā in your own body.
You can start your own research with ā2016 nobel prize in physiology or medicineā.
Or if you want to start with something more practical, you can start your own research with āDr.Valter Longoā.
Thereāre huge information for this health pill rabbit hole, so I canāt digest everything for you (especially if you walled yourself from understanding them). Its your own and your loved ones health (not mine) so you should DYOR.
Iām not forcing you to do the research, its your choice to take the pills.
Ps. Iām not forcing you to trust this, Iām actually a licensed pharmacist (I mainly work in industrial sector, not clinical tho, but I also work in clinical sector as part-time).
And I found a lot of these ānatural house keeping mechanismsā make more senses than a lot of clinical practice guidelines. 
Someone's running a fasting clinic in Cali(?), where they managed to cure cancer and made all the scientific paperwork, but I feel like it's not Longo. Am I wrong?
I dunno, data is somehow abundant but also limited, because thereāre no ācentral guidelines issuersā. Just those who practices and sharing their results. There could also be some deviation among different practioners, but I think thereāre also some major intersection point such as avoid ultra-processed food, avoid seed oil, eat real food.
Because its a free market, everyone doing and eating what suits them best. And difference in culture, food preferences can lead to some small different among them.
Your thinking is backwards.
You got a number of alternative treatments that supposedly disprove the mainstream notion that cancer doesn't have a cure or it requires treatments that do harm.
If one of those treatments fails, that doesn't mean that that notion is true (what you seem to assume). But if only one succeeds, that does mean that mainstream medicine is false.
